Syntheses of 4-methoxymethylbenzyl permethrinates containing fluorine and their insecticidal activity
In order to investigate the relationship between the position of fluorine atom and insecticidal activity about 4-methoxymethylbenzyl permethrinates containing fluorine, 2 and 3-fluoro-4-methoxymethylbenzyl (±)-cis-permethrinate were synthesized. Their insecticidal activities were tested and the fluorine effect of title compounds was discussed.
